Obama, Lady Gaga and Steve Jobs—what do they have in common? They are, of course, all Americans. And according to a survey by social networking site baidu. com, they all best illustrate(举例说明) the word “cool”.

    But just what does it mean to say someone is “cool”? Most would answer that it is something to do with being independent-minded and not following the crowd.

    Yale University art professor Robert Farris Thompson says that the term “cool” goes back to 15th century West African philosophy. “Cool” relates to ideas of grace under pressure.

    “In Africa,” he writes, “coolness is a positive quality which combines calmness, silence, and life.”

    The modern idea of “cool” developed largely in the US in the period after World War II. “Post-war 'cool' was in part an expression of war-weariness (厌战情绪), . . . it went against the strict social rules of the time,” write sociologists Dick Pountain and David Robins in Cool Rules: Anatomy of an Attitude.

    But it was the American actor James Dean who became the symbol for “cool” in the hugely successful 1955 movie Rebel without a Cause. Dean plays a tough guy who disobeys his parents and the authorities. He always gets the girl, smokes cigarettes, wears a leather jacket and beats up bullies. In the movie, Dean showed what “cool” would mean to American young people for the next 60 years.

    Today the focus of “cool” has changed to athletics (体育运动) stars. Often in movies about schools, students gain popularity on the athletics field more than in the classroom. This can be seen quite clearly in movies like Varsity Blues and John Tucker Must Die.

    But many teenagers also think being smart is cool. Chess and other thinking games have been becoming more popular in schools.

    “Call it the Harry Potterization of America—a time when being smart is the new cool,” writes journalist Joe Sunnen.

    International travelers, whether traveling for business or pleasure, will find themselves solo from time to time. Here are a few ways to meet new people and perhaps even get new travel chances.

    Make yourself friendly

    Be relaxed and polite. Remember to put yourself in social activities. Restaurants, shops and parks are all great places to meet people. If you want to make local friends in a country, stay near the place the locals often visit.

    Show your photo album（影集）

    Keep a small photo album in your bag when you travel. Photos of family, friends and pets will help your new friends learn more about you and give you things to talk about. They will share their own stories with you, and it will help you learn more about your new friends.

    Share something special

    Can you help your new friends improve their Chinese? Can you cook a traditional Chinese meal? By sharing your skills, you can have a close friendship with your new friends that they won't soon forget.

    Give some gifts

    Many foreigners love Chinese goods but have to pay a lot when buying them in their homeland, so you'd better prepare some gifts such as silks, tea and works of art. They are always popular.

    Exchange flats

    If you and your new friends get along well, you can give them your information and plan to exchange flats for your next trip. Then you can visit their countries and stay in their houses while they stay in yours. In this way you will improve your friendship and live like a local abroad, but pay less for traveling.

    “I never wanted to come on this stupid hiking trip!” Jeff's voice was panicked. His father stopped and turned to look at the boy.

    “This is hard on you, son. But you've got to come through with your courage.”

    “But I am scared!” Jeff shouted.

    “Please have enough love for your brother to think this through!” His father replied, “We just don't have the time to stop. And I don't know if I can make it without stopping every so often. While you're only ten, you're strong and fast. Do you remember the way back from here to the road, if you had to go alone?”

    Jeff flashed back to the painful scene of his seventeen-year-old brother Mark at their campsite. He'd been bitten by a snake during a rough hike. He needed medical attention right away. Worse still, their cell phone was dead.

    “Jeff? Could you make it to Flint without me? You can get help there.”

    Jeff nodded, said goodbye to his father and continued climbing over the rocks. The rocks and branches threatened his footing and speed, but stone by stone, he made his way up the valley.

    Jeff turned and made the final climbing-up toward the road. When he reached it, he rested himself, breathless. “Can't stop,” he thought. “Mark's in big trouble Keep going.” Just as he pulled himself upright, a truck sped by, heading for Flint " Hey!” he shouted excitedly, waving both arms. The truck stopped, "Jump in, boy! What's up? "The driver asked, Jeff got in and explained. Immediately the driver reached for his cell phone. “Help! Help! Better get the helicopter in there,” he seemed to be shouting into his hand. But Jeff wasn't sure about that because everything got unclear and then went black and quiet.

    Hours later, Jeff opened his eyes to find himself in a hospital, with his father nearby. His father told him that the helicopter airlifted Mark to the hospital and he would be fine in a few days. His father hiked himself out of that valley and took a ride from someone to the town. “You're a hero, son,” his father finally said with a smile.“ You saved Mark.”
